The present invention relates to new compositions and reactions to produce allylic alcohols or precursors of allylic alcohols (e.g., silyl ethers of allylic alcohols). Methods of the invention may comprise combining an alkene and an aldehyde in the presence of a transition metal catalyst (e.g., a nickel catalyst) to form an allylic alcohol or precursor of an allylic alcohol. Reaction products of the present invention may be valuable as intermediates and/or products in pharmaceutical and polymer research. Also, methods of the invention may be useful as fragment coupling reactions in complex molecule synthesis. Moreover, methods of the invention may include the use of reagents which, under reaction conditions known in the art, may have been unreactive, i.e., may not have been able to form the reaction product. The reagents used in the present invention may be relatively lower in cost than in other methods. Also, methods of the invention may reduce the number of synthetic and purification steps required to produce the reaction products, as well as reducing time, cost, and waste production.
本发明涉及新的组合物和反应,用于生产烯丙醇或烯丙醇的前体(例如,烯丙醇的硅醚)。本发明的方法可能包括在过渡金属催化剂(例如,镍催化剂)的存在下结合烯烃和醛以形成烯丙醇或烯丙醇的前体。本发明的反应产物可能作为制药和聚合物研究中的中间体和/或产品具有价值。此外,本发明的方法可能作为复杂分子合成中的片段耦合反应有用。此外,本发明的方法可能包括使用在艺术中已知的反应条件下可能无反应的试剂,即可能无法形成反应产物。本发明中使用的试剂可能比其他方法中的试剂相对较低成本。此外,本发明的方法可能减少生产反应产物所需的合成和纯化步骤的数量,以及减少时间、成本和废物产生。
